Abstract

Abstract : Nanolithography has propelled faster computer chips and even smaller electronic devices, but this patterning technique has not seen widespread adoption for making structured electrochemical materials. A prominent nanopatterning platform championed by numerous semiconductor manufactures is block copolymer lithography. Block copolymers spontaneously self-assemble at the molecular level and they can be directed into long-range ordered, perfect structures via directed self-assembly. Hence, they are attractive candidates for systematic study relating nanostructure to charge-transfer kinetics and transport phenomena. This report highlights the use of block copolymers to study ionic conductivity in microphase separated polymer electrolyte films and for patterning bulk ion-exchange membranes and glassy carbon substrates.
